Description

CVSS: CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:L/I:L/A:N/E:X/RL:O/RC:C (4.0)

Problem

Given that there are at least two different sites in the same TYPO3 installation - for instance first.example.org and second.example.com - then a session cookie generated for the first site can be reused on the second site without requiring additional authentication.

This vulnerability primarily affects the frontend of the website. It's important to note that exploiting this vulnerability requires a valid user account.

Solution

Update to TYPO3 versions 8.7.55 ELTS, 9.5.44 ELTS, 10.4.41 ELTS, 11.5.33, 12.4.8 that fix the problem described above.

Credits

Thanks to Rémy Daniel who reported this issue, and to TYPO3 core & security team member Benjamin Franzke who fixed the issue.

How to fix

Move to the fixed version or later with your package manager, update the lockfile, and run your tests. If the package only arrives through another dependency, upgrade that dependency first. If none of its releases pulls a fixed version yet, force the version with your package manager's override.

Weakness

CWE-287: Improper Authentication

When an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct.

How to prevent it
  • Architecture and Design: Use an authentication framework or library such as the OWASP ESAPI Authentication feature.

CWE-302: Authentication Bypass by Assumed-Immutable Data

The authentication scheme or implementation uses key data elements that are assumed to be immutable, but can be controlled or modified by the attacker.

How to prevent it
  • Architecture and Design, Operation, Implementation: Implement proper protection for immutable data (e.g. environment variable, hidden form fields, etc.)
